Newbie getting married at Dreams Riviera Cancun May 20, 2013!

Hello fellow brides! I would like to congratulate everyone. I've been lurking around this site for quite some time and wanted to introduce myself. Now that we are 5 months away, I still have a lot of unanswered questions regarding ceremony music and knowing how long i should have my selected songs playing for the wedding party's entrance and bride entrance, etc. I planned on using a cd for the ceremony and having the DJ for the reception, about 3 hours since its expensive, about $900. If anyone knows how this works, please let me know. The wedding coordinator from Dreams that I am working with is Evangelina. She has been helpful and very responsive. I have been trying to send her emails with multiple questions to avoid a lot of back and forth. She sent me everything from menus, to lighting, center pieces, bouquets, etc. if anyone needs them, let me know and I will forward them. Happy Planning!
